Where can we get info on what MTP is,aisde the fact that it will take more GB on the HDD?
Edit, found on the FAQ:

The MTP (Merkle Tree Proof) algorithm was devised by Alex Biryukov and Dmitry Khovratovich from the University of Luxembourg in their paper published on the 11 June 2016 titled Egalitarian Computing. These are the same researchers who came up with Equihash that is currently used in ZCash and the Argon2 key derivation function.

MTP promotes fair and democratic mining by making ASIC development expensive. The key element of this approach is large (in size) and intensive (in bandwidth) use of RAM. RAM is expensive in both FPGA and ASIC and slow on GPU. Previous attempts in large and memory intensive proof of works were problematic. This is because to verify these memory intensive proof of works, the nodes had to also have that memory and spend a relatively long time calculating it. This made the network susceptible to transaction DoS attacks where nodes are constantly occupied in verifying transactions.

MTP’s advancement means that hard memory intensive proof of works can be verified quickly with low resources. MTP was designed to be able to require miners to utilize large amounts of RAM up to potentially 10 gb while remaining fast to verify! This can potentially revolutionize PoW mining by bringing it closer to the original vision of Satoshi where one CPU = one vote and democratizing mining instead of keeping it within a handful of powerful miners while maintaining a resilient and low resource network of nodes.

Is it 10 Gb of system ram or GPU ram?
Will that works with 3 GBytes (gtx 1060)?

https://github.com/zcoinofficial/ccminer says:

"mtp requires 4Gb of vram, hence cards with less than 4.5Gb of vram won't work. while running, ccminer will also use around 5.5Gb of ram."

I've tested the miner on a GTX 960 4GB, and it didn't work, as expected. GTX 1060 6GB and GTX 1070 8GB were fine, though slower than expected, both around 100 kh/s.

Women on the Block Sponsorship Announcement: ZCoin
https://medium.com/women-on-the-block/women-on-the-block-sponsorship-announcement-zcoin-5ec4eb10245

Women on the Block is pleased to announce that Zcoin is a sponsor of the “Women on the Block Asia 2018” Blockchain Conference taking place in Singapore on November 14, 2018. Zcoin (XZC) is an open source, decentralised privacy coin that focuses on achieving financial privacy for its users while transacting on the blockchain and also egalitarian distribution of its coins.It pioneered the use of the Zerocoin protocol which uses zero-knowledge proofs in its privacy scheme to break transactions links between transactions and also the first to go live with the Dandelion protocol which hides the originating IP of a sender without the use of TOR or VPNs. Zcoin has been live since September 2016 and is traded on the world’s top cryptocurrency exchanges such as Binance, Bittrex and Huobi. For more information, visit https://zcoin.io

Women on the Block presents a day of learning and thought leadership around blockchain technology. The full day conference will begin at 9:00 am with speakers on topics including Blockchain 101, how to launch a blockchain startup or to be an investor in one, blockchain and law, coding and smart contracts, financial inclusion and economic development and other use cases of blockchain. The conference will also feature keynote speakers unique to the blockchain, cryptography, and digital assets space. Tickets are now available on the Women on the Block website or by clicking this link here.

World’s first large scale blockchain based political election held on Zcoin’s blockchain

Over the period of 1st to the 9th of November, some of you have noticed that we had a huge surge in transactions, with hundreds to thousands of transactions being posted each block on Zcoin’s blockchain. We are now finally able to reveal what these transactions were. In fact this was hinted back in October with Mr. Korn Chatikavanij, former Minister of Finance revealing that political parties in Thailand have started using blockchain technology to select party leaders.

The Thai Democrat Party, Thailand’s oldest political party, recently held a primary election to elect its new party leader. In the past, the party leader was selected by the party’s MPs and the party chairman. With the primary election, all Democrat party members were eligible to vote and it represents the first time a Thai political party has selected its head with input from the grassroots.

what's the best miner for zcoin at the moment?

"Lyra2z was released by Allmine and most BCU1525 owners are mining with it"
Zcoin is mostly mined by FPGAs...

PD: Zetheron miner: Lyra2z   20.5Mh/s   150W

it's great if a team project is active in the community so we don't hesitate to invest here, hopefully this will be a long-term project for all of us and not burdened with prices on the market

[Simss]

Finally Zcoin deposits are activated on Upbit Korean exchange. But the only pair they have is with btc. Would be cool if they had KRW too but step by step.

Work continues! Please find our latest development update on our blog.

Zcoin 0.13.7.2 Released https://twitter.com/zcoinofficial/status/1066042560647356417

This release greatly improves Znode synchronization, includes an Exodus code cleanup which also disables it by default and fixes some smaller bugs.

[CarlOrff]

Since a few days, I have a problem with one ZCoin masternode :

error: couldn't connect to server

I updated to the last version, 0.13.7.2, but same error (https://github.com/zcoinofficial/zcoin/releases)

When I launch the daemon, it run a little less than one minute, and it deconnect to server...
The VPS was runing fine since 6 months.
I tried to reboot the VPS, but always the error.

Any idea ?

Edit :
I reinstall all the VPS (Ubuntu 16.04, ZCoin 0.13.7.2) and allway the same error : the daemon is runing less than one mn (about 100 blocs sincing) and shut down...

Hi, BitBill wallet will support XZC very soon.

Issue solved : that was a hardware issue in the VPS provider...
I loose one masternode reward (15 XZC) :-(.

Personally, I updated my wallet to version 0.13.7.2, and yes the wallet synchronization is much better than it was before.

Zcoin 0.13.7.2 Released https://twitter.com/zcoinofficial/status/1066042560647356417

Has everyone had to upgrade their wallet to the version (0.13.7.2)?
Or just a optional, and only guys want to have better experience with sync process should update their wallets?

[zcoinofficial]

0.13.7.3 is released though the next release which should be quite soon greatly increases sync speed and reduces data consumption.
